A liquid of density `rho` is filled in a U-tube, whose one end is open & at the other end a bulb is fitted whose pressure is `P_(A)`. Now this tube is moved horizontally with acceleration `a` as shown in the figure. during motion it is found that liquid in both column is at same level at equilibrium if atmospheric pressure is `P_(0)` then value of `P_(A)` is

Text Solution

Verified by Experts

The correct Answer is:
C

Consider a point B at the horizontal portion of tube, pressure from both side should be some.
`thereforeP_(0)+rhogh=P_(A)+rhogh+rhoal,P_(A)=P_(0)-rhoal`
